Google Webmaster Tools will give you a list of links pointing to your site, and will show you where the errors come from.

It is possible that over time some scripts have errors and spit out partial URLs that get indexed. These will result in 404 errors and it makes sense to 301 redirect these to the obvious intended page, or your home page. May as well use the link rather than let it go to waste.

Thanks for your reply!
I redirected all the crawl errors and think webmaster will resolve them soon.

I still got problems with this guys
google Webmaster keeps spitting out the strangest url's like:"man-7t-truck-milgl-6x6-info/vehicle-info?_escaped_fragment_="
now whats that?

This day alone I got 34 new errors.

I also got url's like this:"aavp-7a1-ram-rs-build-log-part-07-finished-the-aavp-7a1/feed/"
note the "feed" part

And this:"aavp-7a1-ram-rs-build-log/united-states-armor"
where there is no post named "aavp-7a1-ram-rs-build-log"
and the part "united-states-armor" is the category BUT that category got deleted BEFORE I even added the vehicle "aavp-7a1-ram-rs" (where the first part before the slash comes from).
